What is the yield of thistle per mu?

Thistle is a common recommendation in stone edge and sandy grass, alias grass, white milkweed, with the effect of heat-clearing and detoxification, tonifying the kidney, is widely used as medicinal materials, how much is the yield per mu?

First, how much is the yield per mu of thistle?

The yield per mu of thistle is about 200 jin. If it is managed properly, it can produce more than 200 jin per mu, or more than 100 jin if it is poor. In order to achieve high yield, it is necessary to choose some loose, fertile and humus-rich soil to plant, and to apply sufficient basic fertilizer before planting, and to do a good job of water and fertilizer, weeding and so on in the later stage.

Second, how to plant thistle?

1. Land selection and preparation

Thistle grass is suitable for growing in fertile and loose soil, so try to choose sandy loam with sufficient fertility when selecting soil. After selecting the soil, turn the soil deeply and apply 2500 kilograms of rotten farm manure and 50 kilograms of calcium superphosphate per mu.

2. Sowing and raising seedlings

The main results are as follows: (1) Propagation method: thistle can be propagated by direct seeding or seedling transplanting.

(2) seed selection: the seeds can be collected when the fruit is ripe from July to August each year.

(3) sowing time: there are two methods: direct seeding and strip sowing. Among them, the live broadcast is sown in spring in mid-late April or in autumn from October to November. It is broadcast in March in spring.

(4) sowing method: direct seeding is to trench according to the distance between rows and 20cm, sow the seeds evenly into the soil, and finally cover the soil by 1-2 cm. Generally, 0.75-1 kg per mu can be used for seedling emergence and transplanting after half a month. Strip sowing is to cover 1 cm of soil after sowing, keep the seedling bed moist at all times, control the temperature at 15-20 degrees, emerge after about 10 days, and transplant when the seedlings grow to 6-10 cm.

3. Transplanting

(1) transplanting time: try to choose in the afternoon after cloudy and rainy days, when the survival rate is high.

(2) transplanting method: dig out the plant with soil and roots, and transplant it to the field according to the row spacing of 20 × 25 cm.

4. Management techniques after transplanting.

(1) weeding frequently: if weeds grow more than plants, they should be pulled out in time so as not to breed diseases and insect pests and affect the normal photosynthesis of plants.

(2) Fertilizer requirements: fertilizer should be applied once a year in spring and winter, which can promote root growth, increase yield, fertilization is mainly phosphate fertilizer, 20-25 kg per mu, in the peak growing season, potassium fertilizer solution can be sprayed to improve plant disease resistance. it has obvious effect on the increase of yield.

(3) Water requirement: the larch grass likes the dry environment, except for the proper watering in the early seed germination period and seedling growth period, it does not need to be watered frequently in the later growth stage, so as not to affect its growth, and it should be drained in time after the rainy season to avoid rotting roots.

(4) cover wheatgrass: annual seedlings, after weeding or growing 2-3 years old, should be covered with wheat straw or wheat bran and sawdust after fertilization and watering, which can strengthen the decomposition of vitamins in the soil, maintain moisture, and reduce weeds. Create a good growth environment for thistle grass.
